He probably won't work very well as an SCP, but here's a character I created last year. He's not really meant for horror, but more of a series. Still, I'll throw him at the public and see what we can do.

He's a tall, pale man in a labcoat. He has brown hair and darkly circled eyes, and has long arms and legs. He wields a giant meat cleaver and the anomalous ability to lock up any living object's joints.

How is what you describe anything at all like a pharmacist? And why a meat cleaver?

I'm going to guess he's some kind of serial killer? …But all there is to him is an anomalous gimmick that helps him kill people. And unless he has enhanced strength and resilience, a meat cleaver is a terrible weapon to bring to a gunfight.

Not enough meat on this idea to be an SCP, and someone with the ability to paralyze people is not enough to hang a tale on unless you can make it really interesting.
